King's Bay Gold Corp. announced that a 161 kilometre high-resolution helicopter-borne magnetic and electromagnetic geophysical survey has commenced over its 100% owned Darkwater Gold Mine at Sturgeon Lake property located approximately 30 kilometres north of Ignace, Ontario in the Valora Area of the Patricia Mining Division of northwest Ontario. The claim units were acquired in late November 2010 via staking and are located along the southwest corner of Sturgeon Lake, adjoining the original patented claims of the past-producing Sturgeon Lake Mine itself.

The survey is the property and is anticipated to provide a valuable tool to aid geological and structural interpretation that may identify extensions to previously-known mineralization and locate new exploration targets. Fugro Airborne Surveys, a division of Fugro Canada Corp., has been contracted to fly the survey at 50-metre line spacings and at 60-metre ground clearance, terrain permitting. King's Bay Gold plans to follow up on the new targets and extensions generated by the airborne survey.

The first exploration of the Darkwater Gold Mine property was performed in 1935-1936 and consisted of surface mapping, sampling and 28 diamond drill holes. The program traced an approximately 300-metre long southeastward-dipping, quartz-carbonate-tourmaline lode gold-bearing quartz vein that is hosted by an intrusive igneous quartz diorite-trondhjemitic sill on the southern edge of the Sturgeon Lake Caldera Complex. Twenty six diamond drill holes, spotted at 15.2 metre (50 foot) intervals, were drilled to intersect the vein at a depth of 38 to 46 metres below surface and the other two to intersect the main vein 92 metres below surface.

The underground exploration program completed in 1936-1937 at the Darkwater Gold Mine consists of a 3-compartment vertical shaft to a depth of 129.2 metres; levels at 38.1 metres (125 ft), 76.2 metres (250 ft), and 114.3 metres (375 ft), and with 1,091.4 metres of drifts, 149.3 metres of crosscuts and 113.4 metres of raises. Work at the mine ceased in 1937. Based on Horwood (1937), the results of the historical surface and underground gold sampling.
